Barcelona manager Pep Guardiola has a squad any manager would love to work with. When all of his players are fully fit, he can choose a starting XI capable of rivaling any in footballing history.
Despite the abundance of talent on show at Camp Nou, there are a number of players that could add real quality to arguably the greatest team in history.
The following six players fall into this category and are feasible targets for the Catalan giants.
The 19-year-old Brazilian has been linked to many of Europe's leading clubs and it is easy to see why.
He has already amassed 15 caps for the national side and has scored an incredible 40 goals in 85 league appearances for Santos.
The striker recently denied that a move to Camp Nou was imminent, but a move still seems likely. Neymar is simply too talented to stay in the Brazilian league and if a transfer does not happen right now, it surely will in the not too distant future.
Carlos Puyol is approaching 34 and while he is still a mainstay in the defense, it may be time for Pep Guardiola to think about his long-term replacement.
Thiago Silva would be the perfect solution. The Brazilian could become the perfect partner for Puyol and Gerard Pique when Guardiola decides to use three central defenders.
Should Barcelona miss out on Thiago Silva, fans should be more than pleased if Guardiola is able to persuade Mats Hummels to join the club.
The Borussia Dortmund defender is only 23 and despite rejecting a move to Bayern Munich and signing a contract extension until 2014, if the right money came in for him then it may be difficult for the club to refuse.
Hummels is enjoying a growing reputation in the Bundesliga, but the chance to showcase his talents at Camp Nou could elevate his status to world class.
With Eric Abidal only committed to Barca until next summer, signing a new left-back should be a priority for Pep Guardiola.
Lyon defender Aly Cissokho would be a great addition and would become the natural successor to Abidal.
Signing a quality left-back is a tough ask these days and Cissokho is rated as one of the best prospects in Europe.
Barca should do everything in their power to sign him, as he is potentially the next best left-back on the planet and would be a bargain at the reported £8 million.
While the baggage that comes with him is exhausting, it can not be denied that in footballing terms he would add real quality to any side in world football.
At West Ham he single-handedly saved the club from relegation, at Manchester United he became a fan favorite immediately and at Manchester City he captained the club to their first FA Cup since 1969.
The success Manchester City are enjoying now is partly thanks to Carlos Tevez.
The climate, language and style of football at Barcelona would no doubt suit Tevez and could reignite a career that promises so much more.
Eden Hazard's time at Lille must be heading towards its end.
The Belgian has been linked with many top clubs throughout Europe and his performances have raised his transfer value to a reported €40 million.
This is surely far too much and while I believe he will eventually be sold, the fee should hover around the €20-25 million mark.
This would still represent a great deal for the French club who paid nothing for the player. A move would suit all parties and the playmaker's attacking nature would suit Barcelona's style nicely.
